Application of low-frequency oxygen plasma treatment to polyester fabric to reduce the amount of flame retardant agent

Abstract

To reduce the quantity of chemicals required to produce flame retardant polyester fabrics, a low-frequency oxygen plasma treatment at low temperature (<50 C) was carried out before padding the polyester fabrics with alkyl-phosphonatestructured flame retardant agents. The concentration of the flame retardant agent was varied to determine the plasma treatment effect on the amount of chemicals used in the finishing process. All padded fabrics which had pre-plasma treatment or not, were also washed five times to determine the washing resistance. The surfaces of the polyester fabrics were characterized by FT-IR (ATR) and SEM. The flame retardant performances of the polyester fabrics were evaluated by the LOI test. Hydrophilic characteristics of the polyester fabrics were also tested after the plasma treatment. According to the results, the hydrophilic properties of the polyester fabrics improved after oxygen plasma treatment. Moreover, the plasma treatment allowed the reduction of the flame retardant concentration to 50 g/L in the padding system, however, it was out of the optimal concentration range; the chemical amount consumed was half of the maximum concentration without the LOI changing significantly.

Effect of Argon Plasma Treatment Variables on Wettability and Antibacterial Properties of Polyester Fabrics

“…From the FTIR spectrums, it is clear that a higher increase has occurred in the hydroxyl groups which are responsible for improvement in the hydrophilicity of polyester fabrics after the plasma treatment. Actually, polyester has a highly hydrophobic surface because the surface is made up of ether oxygen (C-O-C) linkages while the hydrophilic ester [32,33].…”

Optimization of plasma treatment variables to improve the hydrophilicity of polylinen®fabrics

“…Analysis of surface chemistry of plasma treated samples with X-ray photoelectron spectroscopy would provide quantitative and more accurate information (Ömerogullari & Kut, 2012). Because of the fact that plasma treatment affects only the surface of the fabric without influencing the benzene rings, only the peaks of carbonyl, hydroxyl, and ether oxygen linkages were affected by plasma treatment.…”
